Since you have found old kernels using

Code:

rpm -qa | grep kernel

you can remove the old one simply using, for example

Code:

rpm -e kernel-PAE-2.6.29.4-167

or

Code:

yum remove kernel-PAE-2.6.29.4-167

does it help?

That is not a "problem". Without 'kerneloops', any kernel errors will simply not be automatically reported to the Linux Kernel Development Team. The package is NOT required in any way for proper operation of the OS. However, you may simply re-install it to re-gain the automatic bug report function.

by default, yum will keep 3 kernel versions on your system. the current, and 2 previous. I would recommend that you keep at least 1 previous version in case a yum upgrade hoses your kernel, you can boot to the previous kernel.

(after you have 3 kernel versions installed, yum will start to remove the oldest version when you install a new kernel.)

Proper way:
Modify your /etc/yum.conf file, change the installonly_limit= liner to numbers of kernel you want to keep.

Default is 3.

I would not bother with it, kernel is not that big is it?

Did you really "delete" or you properly removed kerneloops?

really, kerneloops doesn't do much as far as helping you in case of a bug. However, it does give the kernel developers much needed information to fix problems when you send reports to them.
